CORRUGATED ME TALIJC PLATE.

Application filed December 2, 1926. Serial No. 152,251.

My invention relates to means of reinforcing a metallic plate by forming integral corrugations, embossments or ribs therein and resides in the particular and peculiar configuration and relation of the corrugations to obtain certain desired results.

An object of the invention is to form and arrange a plurality of corrugations in a metallic plate So as to obtain a desired proportion between strength, rigidity and resiliency.

Another object of the invention is to obtain this result with the least amount of raw material and to provide a finished article or the least possible weight consistent with strength requirements.

Another object of the invention is to obtain the desired strength, rigidity and resiliency by forming a metallic plate with int egral embossments, each embossment comprising a plurality of constant width parallel central portions which merge together to form constant width end portions and also forming constant width corrugations in the same metallic plate between and parallel to the ad jaeentf end portions of the embossments.

Another object is to provide such a corrugated metallic plate which can be formed by pressing it (when heated, if necessary) between dies which move toward each other in one direction only.

The construction may be used wherever a strong, resilient panel is desired, but is especially adaptable for railway car structures, such as end walls, side or end doors, hopper doors, floors, roofs, etc, and I have shown and claimed herein the construction used as an end wall of a railway car.

It is well known that the end walls of railivay cars are more likely to be broken or otherwise injured than the side walls. This is due to the inertia thrusts and pressures caused by the shifting of the cargoes when the train starts or stops. These thrusts may be local, tending to distort the end in some particular spot, as for example, when a p ece of piping or lumber shifts lengthwise imparting a blow against the end wall ofthe car; or there may be a general tendency to break out the end wall as a whole or tear it away from the framing. For the purpose, therefore, of greater strength anddurability car ends have been constructed of metal plates corrugated or formed with ribs to impart the desired strength, rigidity and resiliency. My construction is especially adaptstronger where able to end walls for railway cars (of any type) because it has the strength to resist the continuous pounding of the shifting loads thereon and has theresiliency necessary to absorb these numerous shocks without distortion. Distortion of an end wall might bend the brake mast, thereby causing interference with the operation of the hand brake mechanism. Furthermore, such distortion m1 ght reduce the end ladder clearance beyond that prescribed by the Interstate Commerce Commission. hen made of several plates secured together the end wall can be made I greater strength is required. A wooden inside lining is required in a railway house car for blocking the lading to and for compliance with the requirements of the Bureau of Explosives of the American Railway Association. Such a wooden lining can be easily applied to my construction.

lYliile I have described my configuration and arrang' nent of corrugations as used to reinforce the plates of an end wall of a railway car, similarly reinforced plates may be used as a side door for a railway car by providing a frame around its outer edges, or such a reinforced plate may be used as an end door of an automobile railway car by providmg the necessary hinges, latches and the usual attachments; also it may be used to reinforce a metallic plate when used as a drop door of a hopper car by providing the hinges and other usual raising and locking mechanisms. 7

Fig. 1.0 shows a modified form wherein the embossmcnts and corrugations are of the same depth and are of constant depth. Fig. 10 is similar to 6.

The end wall structure comprises a panel composed of one or more metallic plates with my particular configuration and arrangement of embossments formed therein. In

Figs. 1 and 2 the embossed plates 1, 2 and 3 extend from top to bottom of the end wall and may be formed with integral flanges 4: along the vertical edges of the outer plates which overlap and are secured to the side wall 5 ot the car by any suitable means. he top edges of the plates are secured beneath the fascia board 7 and the meeting edges ot' the plates overlap and are secured together by rows of rivets 8 and the lower edges of the plates are secured to the end still 9.

Figs. 3 and at show a it m or my invention applied to a gondola. type of railway car wherein only one plate is used to term the end panel which extends from side to side of the ca and ma y be provided along the vertical edges with flanges which overlap and are secured to the side walls by any suitable means.

. The top edge of the plate is secured to a top chord, while the lower edge is secured to the end sill.

The plate is provided with a plurality of parallel embossments, which embossments each comprise a plurality of parallel central portions 11 which are of constant width and preferably of constant depth. These central portions merge together to form end portions 12 at each end of the QHlbOSSHlQHtS which are of constant width and may be shallower than the central portions. l Jhen the central portion is relatively deep the end portions are preferably made relatively shallow at their ends and vary in depth until they merge into the central portion.

The metallic plate is also provided with constant width minor corrugations 13 positioned between and parallel to the end portions 12 of the embossments. When the central portion of the embossments is relatively deep these minor corrugations preferably correspond in depth to the adjacent end portions of the embossments, but it the embossments are or constant depth, then the minor corrugations are preferably also constant in depth and ot the same depth as the embossmeuts.

The outer ends of the embossments and minor corrugations terminate into the plate adjacent its edge ii line with each other and pre'le ably adjacent the frame member (sill, plate stile or post) to which the plate is attached. The inner end of the minor corrugations terminate into the plate adjacent the merger of the central portions of the embossments. The central portions of each embossment and of adjacent embossments are preferably spaced apart distances equal to their widths so as to form a sinuous configuration; furthermore, the end portions of the (illlllOSSlllGlltS and the minor corrugations are preferably spaced apart distances equal to their widths to form a sinuous configuration.

The broad feature of a metallic plate having a plurality of embossments formed therein, each comprising a plurality of central portions which are merged together at the ends of the embossments with the plate also formed with corrugations positioned between tne ends of the embossments is disclosed and claimed in my co-pending application Serial No. 152,252, tiled December 2, 1926.

The drawings illustrate the preferred form or the invent-ion, though is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.
